5 Warnings and Precautions

5.5 Increased Risk of Thrombosis in Patients with Triple Positive Antiphospholipid Syndrome

(Newly added section)

Direct-acting oral anticoagulants (DOACs), including BEVYXXA, are not recommended for use in patients with triple-positive antiphospholipid syndrome (APS). For patients with APS (especially those who are triple positive [positive for lupus anticoagulant, anticardiolipin, and anti–beta 2- glycoprotein I antibodies]), treatment with DOACs has been associated with increased rates of recurrent thrombotic events compared with vitamin K antagonist therapy.

7 Drug Interactions

7.2 Inducers of P-gp

(new subsection added)

Co-administration of BEVYXXA with P-gp inducers (e.g., carbamazepine, phenytoin, rifampin, St. John's wort) may result in a decrease in systemic exposure of betrixaban and its pharmacodynamic effects. Therefore, avoid the use of BEVYXXA in patients receiving P-gp inducers.

8 Use in Specific Populations

8.7 Hepatic Impairment

(subsection revised, additions underlined)

In a pharmacokinetic study, compared to subjects with normal hepatic function, AUC increases of 30% were observed in subjects with mild hepatic impairment. No dose adjustment is required in patients with mild hepatic impairment.

Compared to subjects with normal hepatic function, AUC increases of 57% were observed in subjects with moderate hepatic impairment. The safety or PK of BEVYXXA in patients with severe hepatic impairment was not evaluated.  Avoid the use of BEVYXXA in patients with moderate and severe hepatic impairment or with any hepatic disease associated with coagulopathy.
